In the article, “Dynamic alterations in chemokine gradients induce transendothelial shuttling of human T cells under physiologic shear conditions,” by Jack Y. Lee, Catherine D. Buzney, Mark C. Poznansky, and Robert Sackstein, which appeared in Volume 86, December 2009, of the Journal of Leukocyte Biology (doi: 10.1189/jlb.0309214), the following sentences were printed incorrectly: “With increasing concentrations of CXCL12 in the luminal compartment, transmigrated T cells did not undergo retro-TEM. However, when exposed to abluminal CXCL12, transmigrated T cells underwent striking retrograde transendothelial migration (retro-TEM) and re-entered the flow stream.” The correct sentences are: “With increasing concentrations of CXCL12 in the luminal compartment, transmigrated T cells did not undergo retrograde transendothelial migration (retro-TEM). However, when exposed to abluminal CXCL12, transmigrated T cells underwent striking retro-TEM and re-entered the flow stream.” This article has been corrected online. The publishers regret any inconvenience caused by the error.
